TAG Heuer Formula 1 Chronograph faceted/octagonal Speed chronograph 43mm (crown-guard case)vsZenith Pilot Big Date Flyback

Owners widely praise the TAG Heuer Formula 1 Chronograph faceted/octagonal SPEED chronograph 43mm (crown-guard case) for its cool design, solid construction, and versatility as a daily watch, with many finding it wears smaller than its 43mm case size and offers good value. The stopwatch function is noted as fun, and the double date windows are considered a cool feature by some. However, a significant portion of owners express reservations about the quartz movement, deeming the price point too high for a battery-powered watch, and some find the plastic case design reminiscent of a child's watch. One owner experienced a loss of timekeeping accuracy after several years, and difficulty with battery replacement is mentioned. The fixed bezel is seen as a drawback by one owner, and the resin straps are noted as prone to splitting.

Owners widely praise the Zenith Pilot Big Date Flyback for its visually striking cerulean blue ceramic case and dial, corrugated dial design referencing early aviation, and the satisfyingly smooth action of its flyback chronograph and big date complication. Reviewers and owners alike highlight the exceptional button action and buttery-smooth movement operation, with many noting the big date mechanism's instantaneous, audible, and satisfying change. The 42.5mm case is generally considered to wear slimmer and smaller than its dimensions suggest, though some find the flat wear and lug curvature less than ideal for wrist comfort. One owner notes the watch's impressive lume-filled numerals and artificial-horizon bar at six. On balance, owners and reviewers rate the Zenith Pilot Big Date Flyback highly for its functional pairing of a high-frequency flyback chronograph and big date complication within a modern and visually appealing design.
